Colonic lipomas are rare benign tumors. Surgical resection is the primary treatment, and intraoperative pathology can guide the extent of surgery, avoiding radical procedures for these cecal lipoma cases.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Colonic lipomas are rare, slow-growing benign tumors, often asymptomatic and incidentally discovered.
- Systematic reviews on cecal lipomas are lacking, despite sporadic case reports.
Observation:
- A 44-year-old male presented with an asymptomatic 1.5-cm cecal mass near the appendiceal orifice, found during routine colonoscopy.
- Laparoscopic exploration revealed a congested, erythematous appendix alongside the cecal mass.
- Histopathology confirmed a cecal lipoma with mature adipose tissue and subclinical appendiceal inflammation.
Findings:
- Definitive diagnosis of colonic lipomas via colonoscopic biopsy is challenging.
- A total of 26 cases, including this one, have been reported in the literature from 2000-2017.
- Surgery is the definitive treatment for colonic lipomas.
Implications:
- Intraoperative frozen section analysis aids in determining the appropriate surgical scope, potentially preventing unnecessary radical resections.
- Excision of appendiceal orifice lipomas may prevent future acute appendicitis.
- The prognosis for colonic lipomas is generally favorable, with low complication rates.
